Description

These are teaching models of various protein secondary structures in space fill and stick representations (PDB: 3vjo (https://www.rcsb.org/structure/3vjo)). They include a space fill α-helix and an accompanying space fill water molecule to illustrate the lack of space along the helix’s axis, as well as a straight stick α-helix, kinked α-helix, and anti-parallel β-sheet, all depicted in stick representation. The models are designed to accompany a teaching module illustrating protein secondary structure and function. The printable models are already uploaded to Shapeways.com in the MacroMolecules (https://www.shapeways.com/shops/macromolecules) shop under the name “Helix and Water (Space-fill) (https://www.shapeways.com/product/GWKNBUH4A/helix-and-water-space-fill?optionId=63490993&li=shop-inventory)”, “Alpha Helix_Thick (https://www.shapeways.com/product/ZLGSU6U6Y/alpha-helix-thick)”, “Alpha Helix_Pro-Gly (https://www.shapeways.com/product/QXNKCDP9E/alpha-helix-pro-gly?optionId=63196313&li=shop-inventory)”, and “Beta-sheet_Thick (https://www.shapeways.com/product/EWNPUUTWW/beta-sheet-thick?optionId=63467769&li=shop-inventory)”. The models have been printed successfully using these parameters on Shapeways’ binder jetting printer in the Coated Full Color Sandstone material.
